Overview

Elementary Surveying Geomatics presents basic concepts in each fundamental area of modern surveying (geomatics) practice. While introductory, its depth and breadth also make it ideal for self-study and preparing for your licensing examination. It includes more than 400 figures and illustrations to help clarify discussions. Extensive end-of-chapter problems give you opportunities to review and apply what you've learned.

The 16th Edition is updated to provide a state-of-the-art presentation of surveying equipment and procedures. Rewritten end-of-chapter problems illustrate computational procedures. It also includes new discussions of GNSS precise point positioning, small unmanned aerial systems, new datums and more.

You can turn on auto‑renew in My account at any time to continue your subscription before your 4‑month term ends.

When you purchase an eTextbook subscription, it will last 4 months. You can renew your subscription by selecting Extend subscription on the Manage subscription page in My account before your initial term ends.

If you extend your subscription, we'll automatically charge you every month. If you made a one‑time payment for your initial 4‑month term, you'll now pay monthly. To make sure your learning is uninterrupted, please check your card details.

To avoid the next payment charge, select Cancel subscription on the Manage subscription page in My account before the renewal date. You can subscribe again in the future by purchasing another eTextbook subscription.

Channels is a video platform with thousands of explanations, solutions and practice problems to help you do homework and prep for exams. Videos are personalized to your course, and tutors walk you through solutions. Plus, interactive AI‑powered summaries and a social community help you better understand lessons from class.
